Any idea why or how this keeps happening (and how to stop it) ?!

I have a feeling this is related to sleep enter/exit, but I'm not sure.

Don't let your computer sleep and see if it happens. If it continues, do the retag. Normally when it shows up as RAW Partition in Disk Management, its corrupted RAID Metadata as I mentioned.

Hi all,

Having some trouble with my perc 5i, wondering if I could get some opinions..

I have 8 disks, 4x1TB in one virtual disk on port 0, 4x2TB in the other on port 1.

Consistently, the 2nd disk (#1) in the 1TB vdisk (port 0) 'fails', and needs to rebuilt regularly (disk is missing, have to import foreign config etc). Which it does ok seemingly, then pretty soon after same thing happens all over.

To try to find out what the actual problem is, I've swapped out the disk with another 1TB, which after rebuild shows the same problem, so I don't think it's the disk.

I've swapped the sata cables on both ports to see the it the problem would 'move' to the other vdisk, which it doesn't, so I don't think it's the cable.

So the card.. Can a single port be bad on the card? As I said it rebuilds fine so it's not totally dead, but consistent issues with that port.

Any thoughts? I do have another card to upgrade to, so I'll probably end up doing that but I'd like to know what the issue is. Any way to diagnose the card itself?

btw my setup is ESXI 5, so I don't have access to the LSI/Dell management software, just the BIOS/Ctrl-R and the ESXI vib file support, which does indicate degraded status when it pops.

Thanks!

Well ,the partition seems completely gone and only after initializing it and converting it to a basic volume it would show up as RAW, is that what you mean ?
I had the idea to backup as much data as possible (got about 3TB that I can backup out of the 5TB in use) and re-create the entire array and format a new NTFS partition.

I might try to retag before that as an almost last resort.

btw, if I save my configuration, delete and then load it, is it as good as creating it with the same parameters ?
Can I even create a new array without initializing it ?

Not exactly. It shows up as raw off the bat most of the time. Backup and then try a retag before trying to wipe out the entire array. Do it from the controller bios.

See this How-To: http://community.spiceworks.com/how_to/show/8781-configuring-virtual-disks-on-a-perc-5-6-h700-controller -

Just don't initialize the VD. Look at your current configuration under VD MGMT, write down stripe size, etc. and then press f2, highlight, and delete.

Aside from trying a new card, did you do anything to rule out the power supply? I've read about funny problems people have had related to power. The simple test would be swapping the power cable for the dive that keeps going bad with the drive next to it.

I can't think of an intermittent thing that would cause the card itself to occasionally fail one hard drive, but I don't have the most experience to draw from.

+1 on the power issue.
My array started showing similar behavior due to power supply voltage issues.

Check your 3.3v/5v levels and try to change the power cable going to the disk.
Try another PSU for a while if you can to determine if it's the culprit.

Guys,
I'm planning on upgrading my file server to an ASRock Z77 Pro4 w/ Core i7-3770. Is anyone else running a Perc 6i on the Z77 chipset, and is the pin-mod required? Thanks!

Edit: I'm also going from a 146GB 15k 2.5" drive to a SATA3 SSD w/ 6 GB/s - should I go ahead and put it on the ASRock Sata to get the benefits of Sata3, or keep it behind the Perc6?

I am running my Perc 6/i on ASUS P8Z77-V (plugged to PCI-E x16_3 which is electrically x4) without the pin mode and never had an issue (at least with the known symptoms of lacking the pin mode).

What kind of array are you planning with those SSD's ?
If it's a small # of disks @ RAID0 then the O/B controller would probably be a much better option.

Also, bear in mind that the O/B SATA controller (the Intel one) offers only 2 SATAIII ports, if there are additional SATAIII ports on the board they are from another 3rd party controller (ASMedia in the case of the ASRock) and you can't pair them together for a single array (well, in a SW array you can, but that is a different story).

Sorry I didn't clarify.
My Data array is a RAID10, 4 x 1 TB drives (until 2.5" 2 TB come out reasonably priced), that is staying on the Perc

My OS drive is a 146gb 15k 2.5" drive, that is what will be moving to SSD - no array, just a single drive.

im recommend you do this http://vmsysadmin.wordpress.com/2011/12/09/using-perc-5i-with-esxi-5-2/ will not fix your problem but you can get more info from the megacli so debug it will be easier...
